Yes all the case fans spin.
Not sure when this happened, i have been asked to look at it for a collegue who said it did this when they went to switch it on one day.
The lights come on, the mobo has an onboard power and reset button which is illuminated and these come on.
No changes to the hardware so to speak, for testing it has been completely stripped down to the core parts, i.e. mobo, CPU, 1 stick of working RAM, gfx and psu
